I had used the services of Used Camera Buyer (usedcamerabuyer.com) in the past with good results. However, I am in the middle of a transaction with them that has given me pause. I sent them 2 Canon lenses, accepted their bid, received confirmation that they received the equipment in good condition and that every thing was set. It has been 2 weeks now and I don't have a check. After no response to emails or my initial phone call, I finally got through to the lady who is handling the transaction. She said my check was in the queue waiting to be approved. Sounds to me more like a cash-flow problem than anything else.
